You can use the script 0-companion-script.R to follow along during the talk or to review the plots later.
You only need to install the following two packages (okay, one of them is the tidyverse, so it's a bit more than just two packages).
install.packages(c("tidyverse", "gapminder"))Please feel free to use materials from these slides in your own materials, with attribution.
